The video tutorial explores the metric system's ability to convert between volume and mass. It begins by calculating the volume of a small cube using its dimensions. The tutorial then explains that 1 milliliter of water occupies 1 cubic centimeter and has a mass of 1 gram. This relationship is extended to 37 milliliters of water, which has a volume of 37 cubic centimeters and a mass of 37 grams. The concept of density is introduced, defined as mass divided by volume, with water having a density of 1 gram per cubic centimeter. Objects with a density greater than 1 gram per cubic centimeter sink, while those with less float.

What is the volume of a cube that is 1 cm long, 1 cm high, and 1 cm wide?

• 1 cubic centimeter

• 1 liter

• 1 milliliter

How much mass does 1 milliliter of water have?

• 0.1 gram

• 100 grams

• 1 gram

If you have 37 milliliters of water, what is its mass?

• 37 grams

• 0.37 grams

• 3.7 grams

• 370 grams

What is the formula for calculating density?

• Volume divided by mass

• Length times width times height
